Solving Linear Equations and Verification

The video tutorial explains how to solve an equation by isolating the variable, simplifying both sides, combining like terms, and verifying the solution. The process involves distributing terms, combining constants and variables, and using arithmetic operations to isolate the variable. The solution is verified by substituting the value back into the original equation to ensure it holds true.

What is the first step in solving an equation to find the value of x?

• Isolate the variable on one side

• Divide both sides by a constant

• Multiply both sides by a constant

• Add a constant to both sides
